blackman nuttall windowed sinc, its trivial to change it to ANY other linear 
resampling algorithm, and ive never seen a non-linear one used for audio, and  
u dont even seem to know what linear means ...

well, listen to it, if u hear some aliasing, tell me ill fix it

if u did any double blind listening tests please elaborate against what did u 
test libsamplerate? what samples where used what the results where ...
